mvc:resources Spring mapping not working
提问by Nikita Vlasenko
I am trying to map any requests that come to /views/node_modules/*to /resources/angular_resources/*folder in my Spring project. How could I achieve this?
我正在尝试将任何请求映射/views/node_modules/*到/resources/angular_resources/*我的 Spring 项目中的文件夹。我怎么能做到这一点？
Currently I have applicationContext.xmlfile that looks the following way:
目前我有applicationContext.xml看起来如下的文件：
<context:component-scan
base-package="fomoapp.domain, fomoapp.dao, fomoapp.service" />
<!-- Root Context: defines shared resources visible to all other web components -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:resources mapping="/views/node_modules/**" location="/resources/angular_resources/" />
<mvc:default-servlet-handler/>
Full web.xml:

<url-pattern>*.js</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>/views/node_modules/</url-pattern>
</servlet-mapping>
I tried the solution here: Absolute path in <mvc:resources/> instead of path relative to mapping of spring servlet
我在这里尝试了解决方案：<mvc:resources/> 中的绝对路径而不是相对于 spring servlet 映射的路径
But it does not work somehow.
但它以某种方式不起作用。

Ultimately solved it. The following thread really helped me: Use of multiple "mvc:resources" tag in spring mvc.
最终解决了它。以下线程确实帮助了我：在 spring mvc 中使用多个“mvc:resources”标签。
So, I did the following:
所以，我做了以下事情：
- Remove
<mvc:default-servlet-handler/>fromapplicationContext.xmland add<mvc:annotation-driven />at the bottom instead - Remove
defaultservlet stuff fromweb.xml
<mvc:default-servlet-handler/>从底部移除applicationContext.xml并<mvc:annotation-driven />在底部添加default从中删除servlet 内容web.xml
After doing this I was able to add additional mappings to applicationContext.xml. Here it is:
完成此操作后，我能够将其他映射添加到applicationContext.xml. 这里是：
<context:component-scan
base-package="fomoapp.domain, fomoapp.dao, fomoapp.service" />
<!-- Root Context: defines shared resources visible to all other web components -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:resources mapping="/views/node_modules/@angular/**" location="/resources/angular_resources/@angular/" />
<mvc:resources mapping="/views/node_modules/rxjs/**" location="/resources/angular_resources/rxjs/" />
<mvc:annotation-driven />

If you would like to use tomcat and jsp. You can create a web MVC configurations and register handler to /static/** route
如果你想使用tomcat和jsp。您可以创建一个 Web MVC 配置并将处理程序注册到 /static/** 路由
@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
"classpath:/META-INF/resources/", "classpath:/resources/",
"classpath:/static/", "classpath:/public/" };
/**
*
* @return
*/
@Bean
public ViewResolver internalResourceViewResolver() {
InternalResourceViewResolver bean = new InternalResourceViewResolver();
bean.setViewClass(JstlView.class);
bean.setPrefix("/WEB-INF/views/");
bean.setSuffix(".jsp");
return bean;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);
}
}
Static file can then be accessed from /static/{URL}. Note that in my case I used jasper, tomcat and jstl and static resources were placed under src/java/main/webapp
然后可以从/static/{URL}. 请注意，在我的情况下，我使用了 jasper、tomcat 和 jstl，并且静态资源放置在src/java/main/webapp 下

You should map the static URLs to the Spring servlet, not the default servlet. So your code should be,
您应该将静态 URL 映射到 Spring servlet，而不是默认的 servlet。所以你的代码应该是，
<servlet-mapping>
<servlet-name>fomoapp</servlet-name>
<url-pattern>*.css</url-pattern>
</servlet-mapping>
